Abstract | The invention provides a riser pressure abnormity identification method and device, electronic equipment and a storage medium, and belongs to the technical field of petroleum drilling, and the method comprises the steps: calculating a first trend matching degree between extracted N sections of riser pressure real-time data sequences and extracted N sections of pump stroke real-time data sequences; if the first trend matching degree is smaller than or equal to a first threshold value, a second trend matching degree between the extracted N sections of riser pressure real-time data sequences and each abnormal standard sequence in an established riser pressure abnormal data standard group is calculated; and determining a riser pressure abnormal condition corresponding to the abnormal standard sequence of which the second trend matching degree is greater than a second threshold value. The device comprises a data acquisition module, a data division module, a data extraction module, a trend matching degree calculati |
